单击按钮完成后播放的音频完成时，从其停止的位置重新开始播放音频

Question

我正在播放音频（mySound）作为背景音乐。单击按钮时，应停止背景音频，并开始播放不同的音频（mySound11）。完成此音频后，背景音乐应自动从其离开的位置恢复。我已经尝试过这段代码，但是在mySound11结束后，后台音频还没有恢复。请帮忙。提前谢谢。

的 MainActivity.java

public class MainActivity extends ActionBarActivity {

    MediaPlayer mySound;
    MediaPlayer mySound11;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mySound11 = MediaPlayer.create(this, R.raw.tiktik);
        mySound = MediaPlayer.create(this, R.raw.jhakmaarke);
        mySound.setLooping(true);
        mySound.start();

    }



        public void playMusic (View view){
            mySound.pause();
            mySound11.start();
        }


    @Override
    public void onResume() {
        super.onResume();
        mySound.start();
    }


    @Override
    protected void onPause() {
        super.onPause();
        mySound.release();
        mySound11.release();
        finish();
    }

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

我在Thread的帮助下解决了你的问题。 我按照你的意愿测试它。

int mySound11Duration;
MediaPlayer mySound;
MediaPlayer mySound11;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mySound11 = MediaPlayer.create(this, R.raw.tiktik);
    mySound = MediaPlayer.create(this, R.raw.jhakmaarke);
    mySound.setLooping(true);
    mySound.start();

}
 public void playMusic(View view) {
        if (mySound.isPlaying()) { //check mysound is playing or not
            mySound11Duration = mySound11.getDuration();
            Thread thread=new Thread() {
                @Override
                public void run() {
                    try {
                        mySound.pause();
                        int mySoundPausePosition = mySound.getCurrentPosition();//get the time where the song is paused.
                        mySound11.start();
                        sleep(mySound11Duration);//sleep method causes the currently executing thread to sleep for specified number of time(miliseconds). 
                        mySound.seekTo(mySoundPausePosition);
                        mySound.start();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            };
            thread.start();

        }
      }
    }
